INVENTOR @Sep/7H.' /aser ATTORNEY Patented Feb 1G, 1931 JOSEPH A. FRASER, OF TULSA, OKLAHOMA VENTLATOR DEFLECTOR Application filed May 31,

My invention relates to ventilators and more particularly to ventilator deiiectors, Vthe principal object of the invention being to intercept the breezes which blow relatively parallel with the walls of a structure and divert them into window openings. further object is the automatic adjustment of a deector in relation to the window opening and in relation to the direction of le a breeze, and the actuation of the delector by changing breezes, for directing any relatively transversely blowing breeze through the window opening into the structure.

In accomplishing these and other objects i5 of the invention, l have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective view oi a device embodying my invention and illustrated as applied to a window screen frame.

Fig. 2 is a perspective view of the device partly broken away Jfor better illustration of a dellector vane mounting. y

Fig. 3 is a modified form of the device as applied to a horizontally elongated window opening.

Referring in detail to the drawings:

The numeral 1 (Fig. 1) designates a window screen frame having vertical members or stiles 2 and 3, for supporting a screen covering l of which only a fragmentary portion is herein shown, the screen Jframe representing the frame members of a wmdow opening through which it is desired to direct breezes blowing relatively parallel with the face of the screen or opening.

Paired upper and lower deflector-mountking bracket elements 5 and 6 adapted for 4G attachment to the stiles 2 and 3 of the screen frame 1 comprise horizontally paired legs 7 and 8 for each bracket element, the inner ends 9 and 10 of which are bent outwardly to provide foot portions for attachment oi the legs to the stiles, the outer ends oi each pair of legs being respectively xed in upi per and lower pivot-supporting members or blocks 11 and 12, each of which will be particularly described. A deector vane 18 comprising a U-shaped frame 1e covered 1928. Serial No. 281,981.

by a curtain 15 is pivotally supported by the blocks 11 and 12, the ends le of the frame 14 being loosely mounted on threaded portions'l adjacent opposite ends of 'a hinge pin 17 rotatably mounted in the upper and lower pivot-supporting members 11 and 12. V

The respective frame ends are iixedly secured to the hinge pin by paired 4nuts disposed on each side of the ends threaded on the said threaded portions 16 of the hinge pin, the opposite ends of the hinge pin having cone-shaped pivot points 18 received by recesses 19 inthe inner ends of pivot screws 2O fitted in vertical threaded openings 21 of the pivot-supporting members 11 and 12.

Lock nuts 22 are provided on the pivot screws bearing against opposite faces of the upper and the lower pivot-supporting members for securing the screws in properly adjusted position in view of the relation be-A tween the spacing ofthe bracket elements and the length of the hinge pin, for elhciently engaging the pivot points of said pin.

The brackets 5 and 6 are identical in construction and the outer ends of the legs 7 and 8 of the upper element are retained in spaced and assembled vertical relation with the outer ends of the lower bracket element by a vertical brace 23 and angle braces 2l and 25, said braces being attached to the bracket elements in the manner and by the means hereinafter described.

The outer ends of the pairs of legs i' and 8 of the bracket elements 5 and 6 lit within slots 26 in angularly directed portions 2? oi' the pivot-supporting members 11 and 12, to which they are fastened by screws 28, 29, 30 and 31. f

The screw 28, which iastens the leg 7 to the pivot supporting. member 11 also extends through the upper end i the vertical brace 23 and serves to fasten said brace in assembled position with the member 11 and upper bracket element. The lower end et the brace 23 is similarly attached to the lower pivot-supporting member 12, by the screw 30, and also fastened to the member 12 by said screw 30 is the lower end of the angle braces 24;; the upper end oi said brace being attached at an .intermediate position on the bracket leg 7 of the upper bracket element 11 by means oit a rivet The angle brace Q is attached to the 8 of the upper pivot member in an intermediate position thereon by a rivet 353, and to the lower pivot-supporting member 12 by the screw 51 'that secures theleg 8 of the lower bracket element to the member 12.

The angle braces 24 and 25 provide means for limiting the rotation oi' the deilector vane, and the vanes are stopped in position for most eiifectively directing currents of air into the window opening by a bend at 34 of the legs 7 and 8 of each bracket ele ment inwardly in relation to the window opening whereby the planes of outer portions 35 of the legs pass within the window opening. The upper encs of the angle braces are fixed in the outer portions 35 so that the Vane when. stopped by the angle braces on one or another of the vertically paired legs 7 or 8 is in a. plane intersecting the opening.

The curtain 15 is provided with snap buttons 36 adjacent its frame-engaging edges and is adapt-ed for folding over the trame 14 so that the buttons may engage with eyes 37 or grommets spaced inwardly on the curtain from the buttons for removably fastening the curtain to the frame. Should it be desirable to remove the curtains for cleaning or replacement the buttons are disengaged, thus allowing the curtain to be easily and quickly removed.

In the modiiied Jform of the device shown in 3, a mounting frame 3S comprises upper and lower support rails having angularly extending sides 40 and offset portions 41, and backturned ends 42 for attachment to a window frame which is of fio greater width than an ordinary window, for accommodating a plurality of the defiector vanes 13.

V-shaped bracket elements 44 and 45 are provided extending inwardly from the odset portion 41 toward the window opening, providing vertically paired legs 46 and 47 to pair with the angularly extending sides 40 of the frame, havingr ends engaged with pivot-supporting members fixed to the inner sides of the rails at the juncture of the sides with the offset portion, analogously to the engagement of the legs 7 and 8 with `be pivot-supportingT members in the preferred form. Tie braces 48 are provided extending angularly from upper to lower side members and legs of bracket elements 44. which provide stop elements for the plurality et swinging dei'lector vanes which are pivoted in the pivot-supporting members.

Assuming the device to be constructed, assembled and applied to a window trame as illustrated and described. the deiiector vanes being pivoted on the pointed hinge pin for quick pivotal response against slight frictional resistance, the vane will readily respond to a light breeze. lVhen the breeze is blowing in a` direction relatively parallel with the side of the structure in which the window provided with the vane is positioned, that is, transversely to the window opening, the breeze will influence the del'lector to pivot so that its tree edge is positioned adjacent the vertical edge of the window opposite the side Yfrom which the breeze comes, and the vane will be stopped in such position, for deflecting the breeze into and 'through the window opening into the structure. The operation is illustrated in Figs. 1 and 2. Then the breeze is blowing from the right, a deflector will assume and retain the position occupied by the detlector shown in said tigures. lVhen the breeze is blowing from the left, the breeze will actuate the deflector to pivot and assume a position indicated by dotted lines designated 49 in said figures. dien the breeze is blowing relatively perpendicularly to the window and towards it, the deflector will assume a position indicated by dotted lines designated 50. Thus, any change of direction oi a breeze blowing transversely of the window or towards it will automatically cause pivoting of the deflector vane to a position in which the maximum possible benetof the breeze will be obtained for a room served by the window. A transverse breeze will be intercepted and diverted into the window and the deflector will automatically be accommodated to each different angle of incidence of a breeze to the window.

The preferably fabric cover or curtain may be removed easily for cleaning or replacement.

hat I claim and desire to secure by Letters Patent is: 1. A deflector of the character described, comprising paired brackets having legs adapted for mounting on a frame, a pivot pin, a deflecting vane mounted on the pin, and means including blocks having grooves to receive the bracket legs and seats for the opposite ends of the pivot pin for supportingl the vane from the brackets.

2. In a deflector of the character described, vertically spaced bracket members each including outwardly converging rails having inner ends adapted for attachment to vertical frame members, a block connecting the outer ends of the rails, a recessed screw adjustably mounted in each block, and a vane member including a hinge pin pivota-lly mounted in the recessed screws.

3. In a deiiector of the character described, vertically spaced brackets including outwardly converging rails having inner ends adapted for mounting on vertical window frame members and having their outer ends bent to lie in planes intersecting the window opening, a vane pivotally supported by the outer ends of the rails, and cross members secured to said bent portions for stopping the pivotal movements or" the venes.

4. in a. deiector of tbe character described, vertically spaced brackets including outward- 1y converging rails, a bearing block on each of the brackets at the junction of the rails, a screw adjustably mounted in each block and a vane member including a hinge pin pivotally supported by the screws.
